HINGE DEVICE FOR WINDOWS Filed Dec. 12, 1962 3 Sheets-Sheet 5 Sven E r/c Persson INVENTQR BY MMW ATTORNEY United States Patent El l-GE EEVlCF-J l VEPE GWS Sven Erie Fer-soon, Stow, Uhio (E i 'slust'i'ngen 23, lvialmo 2d, weden) Filed Bee. l2, 1% Ser. No. Middle? 4- Claims. (Ci. l e-$72) This invention relates to hinge devices for closure members such as, for example, windows of the type that are movable about a horizontal axis substantially midway between the top and bottom thereof from a closed position to an open position.

Previously, hinge devices for pivoted windows have consisted of two pins mounted on the sash that fit into a part mounted on the frame. The total load of the sash is therefore on these two pins at all times. For larger windows, and particularly for windows with two heavy panes of glass, this type of hinge device is unsafe and not entirely secure as the pins always have a tendency to move out from the part on the frame, thus causing the heavy loads to be positioned further out on the pins away from their mounting support.

The present invention is an improvement of that of prior Patent No 2,623,767 which is directed to a hinge device similar to that of the present invention in combination with a control device lock to the window sash in a closed position and to secure the window sash in various partly open and fully open positions.

The present invention eliminates the control device and provides a hinge device with a completely open guide and support means on the frame hinge leaf which is encompassed by a vent hinge leaf, a novel pivot pin mounted in the vent hinge leaf and guided and supported in the guide and support means, and a stop means to prevent the window sash from pivoting through an angle substantially greater than 180 from its closed position.

An object of this invention is to provide hinge devices disposed on a horizontal axis on each side of a window to allow the window to be pivotally disposed so as to be movable from a completely closed position to a position substantially 180 therefrom so that both sides of the window panes can be cleaned from one side of the window.

Another object of the present invention is to provide novel hinge devices with means enabling the sash of the window to be easily removed from and secured in its frame.

A further object of the present invention is to provide a construction in which the window sash is movable from a closed position to a slightly open position to remain thereat without any locking means as a result of the weight of the window sash.

An additional object of the present invention is to distribute the load of the sash equally on several points from the closed position to the partially open position and to the position of 130 from the closed position.

Other objects of the invention will appear from the following description. 7

In order to facilitate an understanding of the invention, reference is made to the accompanying drawings in which:

FiGURE 1 is a front elevational view of a window embody'mg the present invention;

FIGURE 2 shows a perspective exploded View through the left hinge device of PEG. 1 showing the various parts thereof;

FIGURE 3 is a sectional view taken on the line lll-lll of the window of PEG. 1 in closed position;

FIGURE 4 is a view similar to FIG. 3 showing the sash in a diilerent pivotal position;

FIGURE 5 is anothr view similar to FIG. 3 the sash in still another pivoted position; and

FIGURE 6 shows a pivot pin.

showing As shown in the drawings, the present invention is embodied in a window comprising a fixed frame 1 and a sash 2 pivotally mounted in the frame by means of two hinge members 3 and 17, to swing about a horizontal aXis intermediate the top and bottom of sash 1. More particularly, the hinge devices of the present invention can be applied to windows similar to those disclosed in prior Patent Nos. 2,694,841, 2,838,109 and 2,845,116, especially the latter which is directed to a window pivoted to the sides of a window frame for free swinging movement therein through an angle of at least In 2 there is shown the vent hinge leaf 3 or pivotable part to be attached to each side of sash 2 through securing means such as screws 2 that pass through spaced apertures (not shown) in base or mounting element 5'. The screws 2 engage threaded holes 4' of a securing member i which is disposed in the side of sash 2. Proiecting out from element 5 there is a back plate 5" from which extend spaced parallel arcuate shaped plates 6 and 7 connected at their outer edge portions by a cover and supporting member 8 which extends from the upper edge of back plate 5" and terminates as shown at 9 substantial- 1y intermediate the hinge lear". A pivot pin iii is mounted in supporting members it provided on each plate just below terminating portion 9.

Each pin-supporting member 11 includes a frustoconical boss 12 (FIG. 6) disposed on the exterior of plates 6 and 7. An inset or conical seat 13 is provided within each frustoconical boss 12; and comrnunicates with an aperture 14 disposed in each plate member 6, 7. The outer portion of end inset 13 has a larger diameter than that of aperture 14. a

Each pivot pin it? comprises, as shown in FIG. 6, a rigid member 15 on which t1 ere is mounted with a press fit segments to which extend through a ertures The segments 16 comprise a body portion 17' which passes throu h aperture 14, a bore 16 of a diameter slightly less than that of rigid member 15, and a flange 17 which fits within inset or seat 13. Thus, as can be discerned, the rigid member 15 is inserted within a bore 15' of one of the segments 16 which is then passed through inset 13 and aperture 14 of one of the pin-supporting members 3..., then another segment 16 is passed through the inset and aperture of the other pin-supporting member. Force is applied to flanges 1'? until they are seated within insets 15. The rigid member 15 can be provided on its exterior surface with outwardly extending projections such as splines to increase the frictional engagement between rigid member $15 and the bore 16 05 segments 16 when assembled in plates 6, '7. In like manner, bore l6 can be provided with serrations or splines while the exterior surface of rigid member 153 is substantially smooth.

The rigid member 15 can be made from metal, such as stainless steel or alunnnum or some light alley, or possibly a plastic while the segments 16 can be made from a material having good lubricating characteristics such as a plastic or alloy.

The pivot pin it; is generally mounted in pin-supporting members ll so as to be rotatable therein but can be rigidly mounted therein if desired.

As can be seen from FIG. 2, the area from terminating portion 9 to the ends of plates 5, 7, in which pivot pin 13 is carried is open in the manner of a stirrup, while t'.e bottom of element 5 cooperates with the bottom edge of back plate 5 to provide a pivot bearing and abutting portion 5' which will be discussed more in detail along with that of terminating portion 9 hereinafter. Spacer elements 6 project out from plate 6 so as to appropriately space the vent hing leaf 3 from sash 2.

The frame hinge leaf or the stationary part 1'7 of the hinge is mounted on the frame 1 of the window for receiving the pivot pin it of the vent hinge leaf 3 to pivotally support the sash therein.

Frame hings leaf or stationary part 1'7 includes a mounting element 18 having apertures 19 therein to receive securing means such as screws 19 in order to mount same on the frame by a securing member 4. Connected to one end of mounting element 18 is a U-shaped member defining a guide and support means having legs 25) and 21. Leg 20 is fixed to mounting element 13 and has a continuation 2i? also fixedly connected to mounting element 18. Legs 22* and 21 are arcuate shaped to define guide means between which an arcuate slot open at its upper portion is provided in which pivot pin it) moves from a position in which the window is closed (see PEG. 3) wherein the axis of pivot pin 10 is substantially intermediate the upper and lower portions of the slot of the guide member to a position when the window is open (see FIGS. 4 and 5) wherein pivot pin it) has moved to the bottom of the slot of the U-shaped member onto the support meansthereof. Leg 21 has a portion 21 at its upper end which is substantially parallel with the plane through which apertures 19 are disposed. This portion 21' serves to aid mounting pivot pin it in the U-shaped member. Actually leg 21 appears as a hook carried by the mounting element 18.

As can be seen, the diameter of pivot pin 1% is a slight bit smaller than that of the slot between legs 2i and 21 of the guiding means and support means of the U-Shaped member so that pivot pin 1% can easily move therein and no unnecessary play therebetween is provided.

A back plate 22 is connected to mounting element 13 opposite to that of the U-shaped member and has a pivot bearing and abutting portion 23 at the top thereof. It should be pointed out that upon a close examination of FIGS. 2 and 3, the configuration of vent hinge leaf 3 defined by 6, 7 and 5" is substantially the same configuration as frame hinge leaf l7 defined by Zil, 21, 13, and 22 so that when the vent hing leaf 3 is mounted on frame hinge leaf 17, the plates 6 and 7 encompass the legs 26, 21 of the U-shaped member and pivot pin 10 is guided and supported in the U-shaped member (see FIG. 6). Thus, the abutting and pivot portion 5' engages the abutting and pivot portion 23 to form a secondary pivot so that the window can be moved from a partially open position as shown in FIG. 4 wherein pivot pin 10 is in the lowest position in the U-shaped member defining the supporting means to a fully closed position as shown in FIG. 3 wherein the pivot pin llfi is moved upwardly and disposed substantially at an intermediate position in the guiding means provided by the U-shaped member by exerting pressure on the sash to move it into the closed position. The window in its closed position is supported at two points, pivot bearing and abutting portion 5' on pivot bearing and abutting portion 23 and pivot pin it) against leg 21 of the U-shaped member. The sash is then locked in a closed position by a locking member 24. The distance from pivot bearing and abutting portion 23 to any point intermediate the arcuate U-shaped member is the same. In other Words, the portion 23 is at the center of curvature of the arcuate legs 29 and 21 and the slot therebetween. The distance between abutting portion 5 and the center of pivot 10. is equal to the distance between portion 23 and a point between legs and 21.

Turning again to FIG. 4, it can be seen that when the window is opened by exerting pressure on the lower portion of the sash, the pivot pin It) moves in the guide means of the U-shaped member to rest against and be supported at the bottom of the U-shaped member defining the support means thereof due to the weight of the sash, and the window will therefore remain in an open position of about 15 from the vertical without requiring any means to maintain the window open. It

should also be observed that pivot bearing and abutting portion 5' remains in contact with and supported on pivot bearing and abutting portion 23 when the window is opened to the partially open position of FIG. 4 thereby defining a second supporting point.

In FIG. 5, there can be seen the sash 2 opened to about a position from its closed position of FIG. 3. The pivot pin it} lies on the supporting means of the U- shaped member for supporting the sash as in FIG. 4, and the terminating portion 9 of vent hinge leaf 3 abuts against continuation 28' of the frame hinge leaf 1? to define a stop means so that sash 2 will not be capable of further rotation. \Vhen the sash 2 is in the position as shown in FIG. 5, outer part 33. of sash 2 which carries one of the window panes is pivotally connected to sash 2 so that sash 2 can be opened in order to clean the inside of the window panes. An arm 3... is pivotally connected to outer part 31 and to a movable member 33 which moves along channel 34 of sash 2 to hold part 31 open.

As can be seen the hinge device of the present invention affords a sash to be moved from a closed position, to a partially open position and a position of at least 180 from the closed position without the use of any control means. The hinge device of the present invention also affords easy removal from and reinsertion of the sash in its frame.
